1 Claim.

This invention relates to improvements in cooking ranges or stoves, and particularly to the type wherein a liquid fuel burner is employed as the heating medium.

It is an object of the invention to provide an improved combustion chamber within the range which will increase the heating efficiency of the burner and insure a more even distribution of heat throughout the range without danger of the plates in the immediate vicinity of the fire box burning out.

A further object of the invention resides in providing a device of the above-mentioned character which is simple and durable in construction, reliable and efiicient in operation, and inexpensive to manufacture.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying dIaWing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a perspective view of the range, and

Fig. 2 is a longitudinal sectional view of the range.

In the drawing, wherein for the purpose of illustration I have shown a preferred embodiment of my invention, the numeral denotes the body of the range which includes front and back walls 6 and I, a bottom wall 8, top wall 9 and end walls I0. A series of oven compartments II, I2, and I3 are arranged within the body of the range in spaced relation and the front wall 6 is provided with a hinged door I4 for each oven compartment. The oven compartments are centrally disposed within the body to provide a heat circulating space I5 over the top of the ovens, at the ends, and beneath the bottom. A combustion chamber I6 is provided between the oven compartment I3 and end wall I0, and mounted on the outside of the wall It adjacent the chamber I6 is an oil burner I! which is supported by a bracket I8 attached to the end wall. The burner nozzle I9 extends through the wall It into the combustion chamber, and surrounding the burner nozzle is a reflector plate 20 which is vertically curved and lined with a suitable fire resisting material. The oven compartment I3 has its vertical wall 2| next to the chamber Iii in a line with the burner nozzle, and covering the outer face of the wall 2| is a bafile plate 22 constructed of fire resisting material. The wall 2i terminates just above the plane of the burner nozzle, and the top wall 23 of the oven compartment extends from the wall 2| in an upwardly inclined plane which serves to direct the hot gases from the burner in the direction shown by the arrows in Fig. 2. The hot gases travel the full length of the range across the top of the oven compartments and then down and back across the bottom of the compartments, being discharged through the opening 24 which connects with the flue 25.

With my improved type of range, the reflector plate 20 serves to direct the heat generated by the burner towards the inclined top wall 23 of the'oven compartment I3 which causes the heat to be directed into the heat circulating space. Tests have shown this arrangement causes a more uniform distribution of heat throughout the range and without danger of the parts around the combustion chamber being burned out.

It is to be understood that the form of my invention herein shown and described is to be taken as a preferred example of the same, and that certain changes in the shape, size and arrangement of the parts may be made without departing from the spirit of the invention or scope of the claim.

Having thus described my invention, I claim:

In a cooking range, a body having an outlet flue midway its width at its back, oven compartments in said body disposed in side by side relation to each other and surrounded by a space for circulation of hot gases, said space having its lower portion communicating with the outlet fiue, the oven compartments having side walls spaced from each other to provide ducts between upper and lower portions of said space, a combustion chamber located in the body between a side wall of an end one of the oven compartments and an end wall of the body and at its top communicating with a portion of the space over the end oven compartment, an oil burner having a nozzle passing through the end wall of the body into the combustion chamber and projecting inwardly from the end wall toward the confronting side wall of the end oven compartment, said side wall being of a height disposing its upper edge slightly above the horizontal plane of the nozzle of the burner, the end oven compartment having its top extending at an upward incline from the upper edge of the side wall for the major portion of its width for directing hot gases from the burner at high speed across the oven chamber and into the portion of the space above the oven chambers, a bafile plate upon the side wall of the oven opposite the burner for contact by flame from the burner, and a reflector plate in the combustion chamber mounted against the end wall of the body and formed with a central opening through which the nozzle of the burner passes, said reflector plate being formed of sheet metal and above and below the burner being curved away from the end wall of the body.
